What will you do as an Senior Vision Software Engineer?
As a Senior Vision Software Developer , you will be a technical leader within our R&D team , reporting to the Software Development Manager . You will be the driving force behind the core algorithms that allow our sensors to perceive and reconstruct the 3D world .
We are seeking an expert in classical computer vision, 3D metrology, and signal processing to design, develop, and perfect the high-performance 3D acquisition and calibration algorithms at the heart of our next-generation sensor products .
While this is not primarily a machine learning position, an ML background is welcome as an additional skill and may be valuable in the future. You will join a close-knit, multi-disciplinary team of 14 engineers (software, electrical, mechanical/optical) and will have the opportunity to mentor junior members and lead complex technical projects from concept to completion.
The ideal candidate is a passionate, "hands-on" expert who thrives on solving difficult algorithmic problems and developing production-ready, highly optimized C/C++ code.
We welcome applications from Senior Developers with backgrounds in Physics, Photogrammetry, Computational Geometry, or Robotics, provided you have expert-level C++ skills.
Technical Design & Development:
Design and develop robust 3D acquisition algorithms for our sensors to produce high-fidelity 3D data from 2D images.
Develop and improve critical components of our sensor calibration and acquisition pipeline.
Write and optimize manufacturing software tools (e.g., for focusing, alignment, and calibration) required to build and test new sensors.
Characterize, validate, and document prototype sensor performance, working with the team to integrate final designs for customer use.
Lead technical investigations into challenging acquisition problems and algorithm improvements, producing reports and documentation for senior management.
Demonstrate strong ownership, driving complex projects to completion within reliable time frames.
Proactively contribute to and implement continuous improvement initiatives in our development processes.
Note on Seniority: This is a Lead/Principal level engineering role. Candidates must have 7+ years of post-graduate commercial experience in C++ architecture to be considered.

• A Graduate Degree (MS or PhD) in Computer Science, Electrical/Computer Engineering, or a related field with a focus on computer vision or signal processing is strongly preferred.
• 7+ years of professional experience in classical computer vision, 3D metrology, computational geometry, point cloud processing, scene reconstruction, or image-based signal processing.
• Expert-level C/C++ programming skills and a strong understanding of C#.
• Proven experience in independently planning and leading complex software projects from design to completion.
• Deep understanding of object-oriented programming, advanced data structures (lists, trees, binning), and algorithm optimization.
• Solid grasp of memory management, multi-threading, and synchronization.

Please Note: This role does not involve machine learning (ML), deep learning (DL), or AI. Experience in those fields is not relevant for this position.
Preferred Qualifications (Assets):
Previous experience as a team lead, technical lead, or Scrum Master.
Proficiency with scripting languages like Python for testing and tooling.
Health Benefits: Full health care coverage (with 100% paid premiums) including dental, vision, and drugs for you and your family.
A competitive Profit Sharing Program, a Group Retirement Savings Plan, and a monthly internet allowance depending on the location.
An annual Education Support Program for training and professional growth, plus annual performance reviews and Lunch & Learns.
Enjoy free healthy snacks and drinks, team-building budgets, tenure awards, and our official "May the 4th" (Star Wars Day) company holiday!
Wellness: Access to an on-site fitness facility, tennis/basketball court, and company-wide wellness challenges.
To support our collaborative model, preference will be given to local candidates.
Relocation & Sponsorship: Please note that financial relocation assistance and immigration sponsorship are not available for this position.
